JOHN W. MACKENZIE, OF SAN FRANCISCO, CALIFORNIA.

IMPROVEMENT IN FLAG-HOISTING APPARATUS.

Specification forming part of Letters Patent No.126,46l), dated May 7,1872.

I, JonN W. MACKENZIE, of the city and county of San Francisco, State ofCalifornia, have invented certain Improvements in Flag Apparatus, ofwhich the following is a specication:

The object of my invention is to provide an enabling means of clearingiags when foul aloft, vand to avoid the necessity of hauling them downand going through the various ensuing details necessary to clear andreset them, and to avoid the danger of tearing and soiling them. Anotherobject is to provide mea-ns for a neater and more uniform system ofbendingand setting' flags without encroaching upon established forms andregulations. The invention consists, first, of an improved truck, soarranged and combined in structure as to act automatically and in unionwith other means employed and acted upon by the wind. The truck is around metallic box, arranged with a circular opening between the edgesof its upper and lower parts. Its inside contains a carriage uponwheels, movin g upon an inside circular road that is formed upon eitherside ofthe circular opening. Connected with the carriage and comingthrough the opening to the outside is a means for attaching thehalyard-blocks or thimble that is used for hoisting the flag, which isacted upon by the wind, and revolved around and cleared or preventedfrom becoming wrapped around the stati'. The trucks are made of acombination of metals; brass, wrought and cast iron may be used inmaking them; second, upon the lower part of the sta-ft', and inconnection with the truck I use the follower for the purpose of savingthe time and labor of unbelaying and belaying again. The belayed partscan be revolved around to a line perpendicular to the head of the nag.In construction it is a iat metal ring, working in a metal collar, andhaving belaying-pins upon its outer edge. Parts 3, 4, 5, and 6 relate toimprovements that are applied to the flag itself, and having a necessaryand dependent connection in carrying ont the object and purpose of theinvention; third, is the roping of the edges of the flag withhorse-ha-ir twine, thereby making it less prehensile, and preventing itfrom being held Wrapped fast aloft around the stays or other ropes. Thetwine is laid up two-stranded, and made with long jaws; fourth, is aselvagestrap for ting-heads. It is a marled skein, formed with two eyesin its bights, and is put over one partof the eyelet and single part ofthe head-cloth, then the other part of the head cloth is placed over theeyelet and. selvage, then the other plate is placed on and riveted down,showing the selvage between the headcloth. The selvage is used toprevent the twisting ofthe liag upon its head, as is the case when atwisted rope is used; fifth, is an improved brass grummet-buckle. ltsiiange plate is formed with a neck in which the tongue is hinged. Theeyeof the halyards is passed through the gruxnmet and buckled with thetongue. This does away with knotting or toggling. The utility of thisdevice is neatness and despatch in bending. The grummet-buckles may belnade either round or oval; sixth, the improved fair leader is made ofwire, and is formed with a loop in the center. A rightand-left worm isformed on each of its ends. The bight of the hoisting part of thehalyards is turned into the center of the worm, thereby avoiding thenecessity of iinding the end and reeving it through.

Disclaimer.

I do not claim as new the principle of inner wheels working upon aninner roadway, as that principle was patented by me November 12, 1861;neither'do I claim any of the parts embraced in this invention separatefrom the uses and purposes in which they are employed, as set forthherein.

O'Zcim.

I claim- The combination of the roadway b b, metallic box-truck andfollowerfj', constructed and operated substantially as herein set forth.
